25W Ku-Band Transceiver

TRAK Microwave (Tampa, FL) a Microwave brand of Smiths Interconnect, has announced the addition of the HPT Ku-Band High Power Transceiver to its product offerings.

TRAK's new HPT functions as a complete airborne Satcom solution, integrating the necessary GaN SSPA, upconverters, downconverters, and digital control technology to offer a highly modular yet easily maintained system complete with advanced interoperability features and multiple Built-in-Test (BIT) functions. For applications that require additional commercial air transport use assurance, an optional vibration insensitive OCXO installed on a vibration isolation platform is available.

The HPT can transmit from 13.75 to 14.5 GHz from an IF frequency of 950 to 1700 MHz with a gain variation of less than 1.0 dB over any 36 MHz band and provides the frequency block down conversion from 10.7 to 11.7 GHz to the low band IF of 950-1950 MHz or from 11.7 to 12.75 GHz to the high band IF of 1100-2150 MHz. The Receive bands are selectable with commands over the Ethernet bus.

Thermocouple Simulator-Calibrator

Ectron Corporation's (San Diego, CA) Model 1140A thermocouple simulator-calibrator provides four calibration functions: precise simulation of thermocouple signals, precise measurement of thermocouple signals, generation of accurate DC voltages from microvolt level to ±11 volts, and measurement of DC voltages over the same range.

Using a high-speed microcontroller, the 1140A offers such features as an autozero function to correct the zero reading of a non-ideal thermocouple. For repetitive operations, 100 sets of operating conditions can be committed to memory for future retrieval, including automatic sequencing from one condition to the next. Using one of several interfaces, all functions can be programmed and executed under computer control. With an output impedance of less than 0.05 Ω on all ranges, high accuracy is maintained with an absolute minimum of loading error.

Fiber Optic Sensor Probe

Hal Technology (Fontana, CA) has recently developed and demonstrated a compact, lightweight, rugged, high-temperature-capable, flush-mountable, fiber-optic sensor probe for real-time particulate loading rate measurement. The sensor uses an innovative combination of optical particle sensing technologies and fiber-optic packaging in a rugged, compact and non-intrusive optical design. The fiber optic approach separates the electronic components from the extreme harsh environment to prevent direct exposure. The sensor detects light scattering from moving particles as optical pulsed signals whose amplitudes are proportional to size and whose number is proportional to concentration.

The sensor probe provides good sensitivity to particle size (down to 1μm or less) and has large dynamic range (up to 1mm). The current compact sensor probe head is about a quarter inch in diameter, a little over one-inch long and weighs less than 0.1 oz. After calibration, particle load rate tests with standard ISO medium test dust matched distribution data well and high temperature tests showed negligible change in sensor response.
